Ship protection and monitoring relays ensure safety and a high level of ship electrical system availability by monitoring electrical power (voltage, current, and frequency).An impo... Read more
These are used as an accessory for large contactors and are connected through control circuits where they are used for monitoring purposes. Side-mounted contact reference numbers,... Read more
A contactor is used to switch larger amounts of electrical power through circuit contacts of 10 amps or higher. Contacts, carrying such a load are called ‘Main Contacts... Read more
When preparing a ship spares order, the reference numbers or letters should not be ignored, particularly If the requested type of relay is not available from the supplier and anoth... Read more
The modular system is formed around basic units, Which are equipped with additional functions by means of modules. In addition to basic unit contacts, top-mounted auxiliary contact... Read more
The contacts of electromechanical devices on ship electrical system are utilized through control circuitry only are unlikely to sustain currents higher than 10 Amps. They are calle... Read more
Latching relays allow the circuit to be controlled by using a single pulse to the relay control circuit and are used when a relay is required to maintain its position if the power... Read more
The relay is an electro-mechanical switch, consisting of a coil, an armature, and contacts. A current passes through the coil creating a magnetic field that attracts the armature,... Read more
Contactor and relay terminal markings should conform to DIN EN 50005 standard. The markings make it possible to determine the terminals that are associated with the ship component,... Read more
Overload relays protect motors from overheating, eg by machinery being overloaded or an open phase In a three-phase system.The relay will open and disconnect from the power source... Read more
