About Mitsubishi S-N25 Contactor
A contactor is an electrical device which is used for switching an electrical circuit on or off. ... These contacts are in most cases normally open and provide operating power to the load when the contactor coil is energized. Contactors are most commonly used for controlling electric motors.Designed for Efficiency and DurabilityBuilt with a flame-retardant plastic and metal housing, the Mitsubishi S-N25 ensures both safety and longevity. Its high mechanical and electrical life cycles make it a preferred choice for continuous operation in industrial settings. Advanced protection mechanisms preserve critical components and extend service intervals.
Flexible Installation OptionsThe S-N25 offers compatibility with both DIN rail and panel mounting, allowing easy integration into varied electrical systems. Its screw terminal and connector types, together with standard dimensions (80mm x 45mm x 98mm), provide secure and straightforward wiring for three-phase power applications.
FAQ's of Mitsubishi S-N25 Contactor:
Q: How do I install the Mitsubishi S-N25 Contactor in my electrical system?
A: The S-N25 can be mounted on a DIN rail or panel, using standard screw terminals for secure electrical connections. Ensure the ambient temperature is within -5C to +40C and follow the wiring diagram provided in the manual.
Q: What applications is the S-N25 Contactor best suited for?
A: This contactor is ideal for power control and three-phase motor starters in industrial and commercial installations, thanks to its high reliability, built-in thermal protection, and compliance with IEC/EN 60947-4-1.
Q: When should the contactor be serviced or replaced?
A: Routine inspection is recommended based on operational cycles. Given its 10 million mechanical and 1 million electrical life, service or replacement should be considered as it approaches these operational thresholds or shows signs of wear.
Q: Where can I use the S-N25 Contactor in terms of environmental conditions?
A: It operates reliably in environments up to 50C ambient temperature, up to 85% relative humidity, and altitudes up to 2000m. The IP20 rating makes it suitable for protected indoor locations.
Q: What are the benefits of using a silver alloy contact material in the S-N25?
A: Silver alloy contacts provide high conductivity and resistance to arcing, resulting in reliable electrical performance and a longer service life, which reduces maintenance needs.
Q: How does the built-in thermal protection enhance safety?
A: The integrated thermal protection automatically disconnects the circuit in case of overheating, preventing potential damage to the connected equipment and enhancing operational safety.
