Description
HAGER Miniature Circuit Breaker 3 Pole 6kA Excellent Circuit Protection
The HAGER MU340A Miniature Circuit Breaker (MCB) is a robust and highly reliable protection device designed for three-phase electrical systems in commercial and industrial applications.
Rated at 40 Amps with a high short-circuit breaking capacity of 6 kA (according to IEC 60898-1), this 3-Pole MCB ensures superior safety by rapidly isolating faults and protecting wiring and connected equipment from overloads and short circuits.
Featuring a C-Curve tripping characteristic, it is ideal for general applications with moderate inrush currents, such as lighting circuits, sockets, and small motor loads.
The unit is designed for standard DIN rail mounting and offers flexibility with connections for both rigid (1-35mm²) and flexible (1-25mm²) conductors, utilizing secure screw terminals for installation.
The HAGER MCB operates reliably across a wide temperature range of -25ºC to 70ºC and maintains an IP20 ingress protection rating, making it suitable for distribution board environments.
By choosing the HAGER MU340A, you ensure compliance with international safety standards and gain a durable, long-lasting component critical for protecting your three-phase electrical infrastructure.
