TBC-463M Miniature Circuit Breaker (MCB) 4P 63A 6kA

Trip Mechanism: The TBC-463M employs a dual-element thermal-magnetic trip mechanism. The thermal element provides time-delayed protection against overload conditions, while the magnetic element offers instantaneous protection against short-circuit faults. The Type C characteristic means the magnetic trip operates between 5 and 10 times the rated current, making it ideal for circuits with moderate switching surges.

Breaking Capacity: With a rated short-circuit breaking capacity of 6kA at 415V AC, this MCB can safely interrupt fault currents up to 6,000 amperes, providing adequate protection for most residential and commercial installations.

Construction: The circuit breaker features a robust thermoplastic housing with flame-retardant properties. Internal components include silver alloy contacts for reliable switching performance and arc chutes for effective arc extinction during fault interruption.

Terminal Configuration: The 4-pole design includes screw-type terminals suitable for copper or aluminum conductors. Terminal capacity accommodates wire sizes appropriate for 63A current rating, ensuring secure connections and minimal contact resistance.

Installation: Designed for standard 35mm DIN rail mounting according to EN 60715. The MCB can be installed in any orientation, though vertical mounting with terminals at top and bottom is recommended for optimal performance.

Compliance: Manufactured in accordance with IEC 60898-1 standards for miniature circuit breakers. CE marking indicates conformity with European safety directives. Additional CB and TÜV certifications provide international recognition of quality and safety.
