4430.2420 – SCHURTER

The SCHURTER 4430.242 is a single-pole, series-trip thermal circuit breaker designed for equipment protection. It provides overcurrent protection at 12 A, with a rated operational voltage of 240 VAC and 60 VDC. This breaker utilizes a thermal sensing element to detect overload conditions, tripping the circuit when the calibrated temperature threshold is exceeded. The 4430.242 is suitable for applications requiring resettable circuit protection, offering a cost-effective alternative to fuses. Its construction is typically enclosed in a flame-retardant thermoplastic housing, providing insulation and mechanical protection. The device’s trip time is inversely proportional to the overload current, allowing for short-duration surges without nuisance tripping while ensuring rapid response to sustained overcurrents.
