Compact circuit breaker LS TS160N FMU 125A 4P

LS Electric Compact Circuit Breakers – Reliable Installation Protection

LS Electric TS160N series compact circuit breakers are a fundamental protective element in any electrical installation. They provide effective protection against overload and short circuit, protecting both devices and the distribution network itself. The TS160N FMU 125A 4P model stands out with its high current parameters and solid construction, guaranteeing long-term and trouble-free operation. It is an ideal solution for both professional installers and end customers looking for reliable protection.

Characteristics and application

This four-pole compact circuit breaker with a rated current of 125A is equipped with an adjustable thermal release (FMU), allowing for precise adaptation to the specifics of the protected installation. The FMU release reacts to the temperature increase caused by overload, disconnecting the circuit before damage to wires or connected devices occurs. The application of this type of circuit breaker is wide – from protecting lighting and socket circuits in residential and commercial buildings, to protecting more demanding industrial equipment. The value of 50kA (at 500V DC) determines the circuit breaker's ability to withstand short-circuit currents, which is crucial for ensuring safety in the event of a failure.

Construction and product features

The TS160N FMU 125A 4P circuit breaker is characterized by its compact dimensions (140 mm width, 160 mm height and 86 mm depth), which facilitates installation even in limited spaces. Solid construction with high-quality materials ensures resistance to mechanical damage and environmental conditions. The possibility of connecting wires both from the top (screw) and from the bottom (screw) increases installation flexibility. The circuit breaker complies with the IEC 60947-2 standard, which confirms its compliance with international safety standards. High resistance to electromagnetic interference (IP20 protection degree) ensures stable operation in harsh industrial conditions. Additionally, the circuit breaker has adjustable thermal operating current in the range of 0.8 - 1 x In and instantaneous operating current at the level of 10 x In, allowing for optimal adaptation to the load characteristics.
