Jistič série 187 – Panelová montáž 90 A

This circuit breaker has a rated current of 90 amperes (90 A), making it suitable for protecting high-load circuits in marine electrical systems.

A circuit breaker protects electrical equipment and wiring from damage caused by overcurrent or short circuits. It automatically interrupts the circuit in case of failure and can then be reset manually once the issue is resolved.

This is a thermal circuit breaker, meaning it uses a heat-sensitive element to detect overcurrents and open the circuit.

This circuit breaker is designed to work with marine electrical systems up to a maximum of 48V DC.

This circuit breaker is designed for panel mounting. It integrates directly into electrical panels or control consoles, requiring an appropriate cutout for installation.

For installation, you will generally need basic marine electrical tools, such as a hole saw or drill for cutting the panel, wrenches for tightening terminals, a screwdriver, and crimping pliers for cable connections.

Yes, it is critical to disconnect all power sources before installation to avoid any risk of electrocution or short-circuit. Ensure that the wiring is correctly sized for 90 amps and that all connections are clean and securely tightened.

This circuit breaker is designed to operate across a wide temperature range, typically from -40°C to +85°C, making it suitable for varied marine environments.

Yes, this circuit breaker is compatible with 12V and 24V marine electrical systems, as well as with DC voltages up to 48V, provided the circuit current does not exceed 90 amperes.

Recommended for protecting high-current circuits such as inverters, bow thrusters, windlasses, high-flow bilge pumps, or main service circuits on board boats.

Although designed for demanding marine environments, this circuit breaker can technically be used in other 12V/24V/48V DC applications requiring 90-ampere overcurrent protection and weather resistance, provided technical specifications are met.

Yes, as a Blue Sea Systems product, it is designed to integrate seamlessly with other brand components such as bus bars, fuse holders, and distribution panels to create a coherent and safe marine electrical system.

Yes, it can replace a 90-amp fuse in many applications, with the advantage of being manually resettable after a trip, which avoids fuse replacement and simplifies troubleshooting.

Yes, it is suitable for protecting circuits powering electric motors, including bow thrusters and windlasses, provided their maximum operating current does not exceed 90 amperes and starting surges are handled by the circuit breaker's capacity.
