£203.85
The ABB S204MC63, also designated SU204M-C63, is a premium four-pole UL489 miniature circuit breaker (MCB) developed for branch-circuit protection in industrial machinery, OEM equipment and control panels. Part of the ABB System pro M compact SU200M series, it complies with UL 489, CSA 22.2 No. 5 and IEC/EN 60947-2, making it suitable for both North American and international markets.
Featuring a C-curve tripping characteristic, the breaker provides dependable protection against overloads and short circuits while accommodating moderate inrush currents from motors, transformers, lighting and automation equipment. Its UL489 certification makes it particularly suitable for industrial branch-circuit protection in export machinery and control systems.
With a 63 A rated current, four protected poles and an IEC rated short-circuit capacity of 11.2 kA at 400 V AC (15 kA ultimate breaking capacity), the S204MC63 delivers robust protection whilst remaining compact enough for installation on standard 35 mm DIN rails.
The ABB S204MC63 has been specifically developed for OEM machinery, industrial automation equipment and export control panels requiring UL489 branch-circuit protection. It delivers dependable overload and short-circuit protection whilst complying with internationally recognised electrical standards.
Its C-curve magnetic trip allows normal motor and transformer energisation without nuisance tripping while still providing rapid fault clearance when required.
