Siemens 5SY4104-6 Miniature Circuit Breaker 4A, 1-Pole, B Curve, 230/400V, 10kA Original Brand New
$9.59
High-performance single-pole Miniature Circuit Breaker (MCB) with a 4A rated current, Type B characteristic, and a powerful 10kA breaking capacity for reliable short-circuit and overload protection in industrial and commercial electrical installations.
Availability: In stock
Overview
The Siemens 5SY4104-6 is a robust, single-pole (1P) Miniature Circuit Breaker (MCB) designed for the reliable protection of conductors against overload and short-circuit faults in standard electrical systems. Part of the highly successful Siemens Sentron protection devices, this MCB is engineered for maximum safety and operational availability in both industrial and commercial distribution boards. Its high-rated 10kA short-circuit breaking capacity makes it suitable for demanding applications under 230V/400V AC. The generous 70 mm depth (D=70 mm) is compatible with standard distribution panel installations.
Key Benefit
-
Reliable Protection: Prevents electrical overloads and short circuits efficiently.
-
High Breaking Capacity: 10kA rating ensures safety even under high fault currents.
-
Compact Design: Slim 70mm depth for easy integration into electrical panels.
-
Durable Siemens Quality: Long-lasting performance with industry-standard reliability.
-
Versatile Applications: Suitable for residential, commercial, and industrial setups.
Function & Application
The Type B Characteristic (tripping at 3 to 5 times the rated current of 4A) makes the 5SY4104-6 ideal for protecting circuits with minimal or no inrush current surges.
-
Function: Interrupts the flow of electricity when the current exceeds the rated value, either slowly (overload) or instantaneously (short-circuit).
-
Primary Applications
-
Protection of standard lighting circuits.
-
Protection of circuits supplying resistance loads (e.g., standard heating elements).
-
Protection of socket-outlet circuits in residential and light commercial buildings.
