CJM5-63 Miniature Circuit Breaker Delivers Reliable 6kA Short-Circuit Protection for Residential and Similar Installations
Versatile MCB supports B/C/D tripping curves, multiple pole configurations up to 63A rated current
[ZHEJIANG, CHINA] – October 21, 2026 — The new
CJM5-63 Miniature Circuit Breaker (MCB) offers robust overload and short-circuit protection for household and low-voltage similar installations, complying with global IEC 60898-1 and EN 60898-1 safety standards. Designed to serve as main circuit switches, this
MCB provides high breaking capacity up to 6000A (6kA), covering rated currents ranging from 6A up to 63A to match diverse load requirements.
Built with clear contact position indication for easy visual status check, the CJM5-63 series supports multiple pole versions including 1P, 2P, 3P, 4P, as well as 1P+N and 3P+N combinations. Users can select B, C or D tripping characteristic curves for lighting, general power, or motor-type load applications respectively. Rated operational voltage reaches 230/400VAC (240/415V) under 50/60Hz frequency.
“The CJM5-63 MCB is engineered for convenient cabinet integration and long service life,” said Product Development Manager. “With standard 18 mm module width, it fits perfectly onto widely-used 35 mm DIN rails and is compatible with PIN busbar systems for fast panel assembly.”
⚙ Key mechanical and electrical specifications of CJM5-63 MCB:
- • Rated Current: 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A
- • Breaking Capacity: 6000A (6kA)
- • Operating temperature range: -5 °C ~ +40 °C
- • Terminal tightening torque: 5 N-m; top & bottom terminal capacity: 25 mm²
- • Electro-mechanical endurance: 4000 operating cycles
- • Compliance: IEC60898-1, EN60898-1
Thanks to compact dimension and complete parameter options, the CJM5-63 miniature circuit breaker is well-suited for residential distribution boxes, small commercial panels and on-site low-voltage power installations across global markets. Installers can quickly identify switch status via built-in contact position indicator to enhance maintenance safety.
