Circuit breaker Legrand 412926 — modular protective device, Width 100 mm, Depth 184 mm, Height 88 mm, pack of 10

Legrand 412926 is a modular protective device supplied in a pack of 10, designed for installation in distribution boards and switchgear. With overall dimensions of 100 mm width, 184 mm depth and 88 mm height and a single-module format, this circuit breaker provides overcurrent and short-circuit protection for residential and light commercial electrical installations. The device integrates a non-replaceable green LED indicator with an expected life of up to 100,000 hours and low LED consumption, and it is compatible with prong-type supply busbars.

Advantages

The modular design and compact single-module width enable easy mounting in standard electrical panels while saving space. The integrated LED indicator offers clear visual status without additional wiring and consumes minimal power (0.17 W at 230 V~ and 0.11 W at 24 V~). Compliance with IEC 60947-5-1 ensures the switching and signalling functions meet recognized safety and interoperability standards. A pack of 10 units simplifies procurement for multi-point installations and reduces handling time for installers.

How to use

Install each modular device into the distribution board rail according to the manufacturer's mechanical mounting instructions and ensure compatibility with prong-type supply busbars. Connect line and load conductors following local wiring regulations and verify tightness of terminals. Use the built-in LED indicator to monitor circuit status; no separate lamp wiring is required. Perform insulation and continuity checks before energising the circuit and carry out a functional trip test after installation to confirm correct protection operation.

Recommendations

For reliable operation, store and install the devices in a dry, dust-free environment and ensure the ambient temperature stays within the limits specified by the electrical panel manufacturer. Regularly inspect connections for tightening and signs of overheating. Replace the entire device at end of life or if mechanical or electrical damage is detected, as the LED is non-replaceable.
