Product Description
SB203M-C16 Miniature Circuit Breaker - 3P - C - 16 A
System pro M compact SB200M Miniature Circuit Breakers are current limiting. They have two different tripping mechanisms, the delayed thermal tripping mechanism for overload protection and the electromechanic tripping mechanism for short circuit protection. They are available in different characteristics (B,C,D), configurations (1P,1P+N,2P,3P,3P+N,4P), breaking capacities (up to 10 kA at 240/415 V AC) and rated currents (up to 63A). All MCBs of the product range SB200M comply with IS/IEC 60898-1, allowing the use for residential, commercial and industrial applications.
Versatile Circuit ProtectionThe SB203M-C16 MCB is ideal for protecting lighting and power circuits in industrial and commercial setups. Its C curve tripping provides optimal response to both moderate and high inrush currents, making it suitable for diverse loads such as motors and lights. Rated for 16A and up to 400V AC, it consistently ensures electrical system safety.
Robust Performance and SafetyBuilt with high-grade flame retardant plastic, this MCB achieves IP20 protection, shielding users against accidental contact with live parts. With a temperature operation range from -25C to +55C and breaking capacity of 6 kA, it stands resilient in demanding environments. Certified according to IEC/EN 60898-1, reliability is assured.
Ease of Installation and MaintenanceThe SB203M-C16 is designed for DIN rail mounting, allowing for straightforward integration into new or existing panel boards. Supporting terminal capacities up to 25 mm2, it accommodates a range of wiring sizes. Its compact modular dimensions and long mechanical and electrical life simplify both installation and long-term servicing.
