Circuit breaker Legrand 412780 Width 84 mm Depth 98 mm Height 22 mm

The Legrand 412780 circuit breaker is a compact protection device designed to safeguard electrical circuits in residential and commercial installations. With a slim profile and shallow depth, this electrical component fits into a variety of distribution panels where space is limited while providing reliable overcurrent protection and switching capability.

Advantages

The circuit breaker combines a small footprint with robust mechanical construction, enabling straightforward mounting and integration into existing switchgear. Its dimensions—width 84 mm, depth 98 mm and height 22 mm—allow for space-efficient layout and simplify replacement of older or bulkier protective devices. The unit delivers consistent tripping response for circuit protection and reduces the need for frequent maintenance compared with fuses.

Suitable for

• Protection of lighting and power circuits in homes and apartments
• Small commercial electrical panels and tenant distribution boards
• Retrofit and replacement projects where panel space is limited
• Workshops and utility rooms requiring compact overcurrent protection

Key specifications

• Physical dimensions: width 84 mm, depth 98 mm, height 22 mm
• Device type: modular circuit breaker for panel mounting
• Mounting: designed for standard electrical distribution enclosures
• Function: overcurrent protection with manual switching capability
• Construction: compact form factor suitable for space-constrained installations

How to use

Install the breaker according to the electrical code and Legrand installation guidelines, ensuring the panel is de-energized before work begins. Mount the device in the distribution board at the appropriate position, make secure conductor connections to the input and output terminals, and verify correct tightening torque. After installation, restore power and perform functional checks by operating the breaker manually and testing the protected circuit under normal load conditions.

Usage recommendations

Select the appropriate trip rating and characteristics that match the protected circuit and upstream/downstream equipment. Regularly inspect terminal connections for proper tightness and signs of overheating, and follow local regulations for periodic testing and maintenance to ensure long-term reliability.
