China Custom Hydraulic, Întreruptoare maritime magnetice unice

Marine circuit breakers, reliable operation at -55℃~125℃, rail installation. AC/DC 1-600A-cable device protects marine circuit breakers. 1-100A can be customized, universal for AC/DC; multiple control modes, carrying 100% curent nominal. Marine circuit breakers are used to resist the excitation surge current when the transformer is first powered on. Among them, the short-circuit protection of the circuit breaker is delayed, that is, adjustable delay S parameter short-circuit protection; the series-connected fuse is used to perform transient short-circuit protection. The two are matched to complete short-circuit instantaneous protection and short-circuit short-delay protection.

Purchase reliable marine circuit breakers for your boating needs. Safety rated and waterproof boat circuit breakers with single lever

Marine overload protection devices meet the following requirements:
Allow normal currents (less than or equal to the rated current of the system or equipment) to flow continuously.
Allow temporary overload conditions, such as those associated with motor starting or capacitor switching, without unnecessary tripping.
Capable of detecting and tripping circuit breakers under overload conditions that, due to the magnitude and duration of their current, can damage equipment insulation or the equipment itself.
When equipment insulation fails, short-circuit currents of the circuit breaker rating may flow many times over. To reduce thermal and dynamic stresses that may occur to system components or equipment, the short circuit should be interrupted as quickly as possible. The rated current of the circuit breaker is the rated current that appears on the front of the product. The generation of the tripping characteristic or time delay curve is based on a percentage of this value.
