Circuit Breakers

LELBXK111-40826-30-V is a type of circuit breaker. Its application field and working principle are as follows.

Application Field

LELBXK111-40826-30-V is a high-end DC circuit breaker designed for use in harsh environments and in areas with extreme temperatures. It is suitable for controlling and protecting low-voltage DC circuits in ships, off-shore installations, power plants, factories, vehicles, and other situations where reliable control and protection are necessary. This breaker can provide reliable protection for all kinds of electrical equipment.

Working Principle

The working principle of the LELBXK111-40826-30-V circuit breaker is based on two principles: over-current protection and short-circuit protection. When a short-circuit occurs on any part of the circuit, the breaker detects the abnormally high current flow and trips the breaker. This prevents the current from exceeding the rated value and damaging the underlying devices. The breaker also trips in case of an overload, protecting the circuit from any damage.

The LELBXK111-40826-30-V also has a thermal overload protection feature. This feature works in case the current flowing in the circuit exceeds the thermal capacity of the breaker. The breaker trips, preventing further damage. This breaker also has internal adjustments for setting the current limit according to the specific requirements.

Additionally, the LELBXK111-40826-30-V has a dielectric strength between poles of up to 1,000V AC and between the line and the ground of up to 3,000V AC. This breaker is also capable of operating from -40°C to +121°C. The breaker can also cut and cover any direct short-circuit between the incoming and outgoing contacts.

In conclusion, the LELBXK111-40826-30-V circuit breaker has many features that make it suitable for a variety of applications, from harsh environments to areas with extreme temperatures. It can provide reliable protection and control in any situation, ensuring the safe operation of the underlying electrical devices.
