The new REX12 electronic overcurrent protection device combination consists of the EM12-T power supply module and the REX12-T electronic circuit-breakers, which can be connected in any modular way on one or two channels. The modules, each only 12.5 mm narrow, are completely designed in push-in technology including orange terminal actuators and therefore enable tool-free, time-saving and maintenance-free wiring.
The power feed module is designed for DC 24 V and 40 A and accepts a maximum of 10 mm² with wire end ferrules for the positive (+) feed. On the load output side, the automatic circuit breaker can be wired with 2.5 mm².
The new REX12 generation combines flexibility with compactness. It is therefore precisely tailored to the requirements of mechanical engineering. No additional accessories are required for the electrical and mechanical connection of the individual components. This saves time and money!
Key features:
- Device combination power supply module and electronic circuit breaker
- Single and dual-channel selective load protection using an electronic switch-off characteristic
