Terminal Blocks, Busbars & Switchgear Accessories
In demanding industrial environments, electrical connections need to be safe, repeatable, and easy to install — first time, every time.
Leveltec is the Australian distributor for Morek, a European manufacturer of electrical connection components trusted by engineers across the mining, rail, shipping, and broader industrial sectors. From terminal blocks and distribution connectors to busbars and switchgear accessories, the Morek range is engineered for harsh-environment performance: tested for short-circuit withstand, certified to international standards, and built to handle the vibration, dust, and load demands of heavy industry.
For electrical engineers specifying connection systems, that means fewer compromises, products rated for both copper and aluminium conductors, Class A short-circuit certification where it matters, and a catalogue broad enough to cover an entire switchboard build from a single supplier.
Through Leveltec, the full Morek range is available across Australia and New Zealand, backed by local stock, engineering advice, and site-ready support.
Applications
- Switchgear and control panels
- Mining and bulk materials handling infrastructure

When performance under pressure matters, Morek components provide the dependable link that keeps critical systems online.
Universal Terminal Blocks for Copper and Aluminium
Morek’s OTL Universal Terminal Blocks are the workhorse of the range, bimetal terminal blocks engineered for both copper and aluminium conductors, with cross-sections from 1.5 mm² up to 300 mm². For engineers specifying connection systems in mining substations, rail traction supply, or shipboard switchboards, OTL terminals remove the need to stock separate copper and aluminium connectors, simplifying inventory without compromising on performance.
Each OTL terminal block is Class A certified to EN 61238-1 and EN 60947-7-1 — tested under both heat-cycle and short-circuit conditions, not just heat cycling alone. That distinction matters in fault-prone industrial networks where a Class B connector simply isn’t built to handle a real short-circuit event.
Key specifications:
- Conductor range: 1.5 mm² to 300 mm² (Cu/Al)
- Voltage rating: 1000V AC / 1500V DC
- Current capacity: up to 980A

Device Connectors and Bow Terminals
Morek’s device connector range covers three distinct series, each designed for a different scale of switchgear connection — from standard DIN rail circuit breakers through to high-current moulded case circuit breakers and ACBs in mining substations and industrial MCC panels.
SR Series — Standard Device Connectors
The SR series connects aluminium and copper cables directly to circuit breakers, contactors, and control equipment, with a self-extinguishing polyamide cover for fire resistance and IP20 protection as standard. Especially relevant where panel space is tight and a direct device-to-cable connection is preferable to routing through an intermediate terminal block, a common requirement in compact switchrooms and rolling stock electrical cabinet designs.
- Conductor range: 6 mm² to 95 mm² (Cu/Al)
- Voltage rating: up to 690V
- Current capacity: up to 320A
- Class A certified (EN 61238-1, EN 60947-7-1)
- Self-extinguishing polyamide housing, IP20 protection
OL Series — Heavy Duty Connectors
The OL series is built for high-current applications where the SR range isn’t enough. Made from stainless steel, copper, and steel components, OL connectors handle conductors from 6 mm² up to 2 × 300 mm² and currents up to 800A — making them a practical choice for large-format MCCB connections, main incomer terminations, and heavy industrial switchgear in mining and industrial plant environments. Stranded conductors can be clamped without modification of wire ends, and installation requires no special tools.
- Conductor range: 6 mm² to 2 × 300 mm² (Cu/Al)
- Voltage rating: up to 690V
- Current capacity: up to 800A (single), up to 800A Cu / 800A Al (twin conductor)
- Stainless steel, copper, and steel construction — suited to harsh environments
OTH Series — Universal Connectors for High-Current ACBs
The OTH series is designed for connecting copper and aluminium cables directly to large switchgear devices accepting two, three, or four conductors up to 300 mm² without cable lugs. Their compact bimetal aluminium alloy body features contact paste on clamping surfaces, oval-shaped holes for flexible cable routing, and profiled slotted holes for a firm, vibration-resistant connection.
Rated to 1000V and 1250A, OTH connectors are verified compatible with major switchgear brands including ABB, Schneider, Eaton, Siemens, Chint, and Schrack Technik.
- Conductor range: 2 × 70–300 mm² or 3 × 70–300 mm² (Cu/Al) + 1 × 1.5–4 mm² indication terminal
- Voltage rating: 1000V
- Current capacity: up to 1250A
- Bimetal aluminium alloy construction, tinned contact surfaces
- Compatible with ABB Tmax/Emax, Schneider NS/NSX, Eaton NZM, Siemens 3VA, Chint NM8N, and Schrack Technik MX series
Bow Terminals MAE
Morek’s MAE Bow Terminals offer a fast, reliable screw-type connection for busbar-to-busbar or busbar-to-device links, a neater and more repeatable alternative to fabricated connections in switchboard builds. Available in both standard and bimetal configurations, they’re suited to mixed copper and aluminium installations common across mining, rail, and industrial plant switchgear.
The bimetal MAE-H variant eliminates the need for additional tin-plating when joining dissimilar metals — a common pain point in mixed copper/aluminium switchboards — while the MAE-E handles same-metal connections from 1.5 mm² up to larger cross-sections.
Key specifications:
- Conductor range: 1.5 mm² to 185 mm²
- Voltage rating: up to 1000V AC / 1500V DC
- Current capacity: up to 500A
- MAE-E: copper-to-copper or aluminium-to-aluminium connections

- Screw-type connection, suitable for DIN rail and busbar mounting
Insulated Copper Flexible Busbars — Moflex
Moflex Insulated Copper Flexible Busbars solve a problem that rigid bar can’t: connecting busbars or devices where the routing simply won’t accommodate a straight conductor. Made from highly flexible copper strip with self-extinguishing PVC insulation, Moflex busbars achieve up to 68% smaller cross-section than equivalent copper cable for the same current rating, thanks to the skin effect benefits of a flat conductor profile.
Rated from –40°C to 105°C and backed by a 5-year warranty, Moflex is increasingly specified in switchboard retrofits and tight panel layouts across mining and industrial sites where space is at a premium and installation time matters.
