Crydom H-A Series Solid State Relay Panel Mount 75A Load 530 V AC Load 280Vrms Control HA4875

Crydom HA4875 is a robust H-A Series Solid State Relay designed for panel mounting with a maximum continuous load current of 75 amperes and load voltage capability of up to 530 V AC. This relay incorporates a zero voltage switching function, enabling precise and reliable control of electrical loads by closing or opening circuits at zero crossing points, minimizing electromagnetic interference and prolonging device life.

Constructed with an aluminium baseplate, the relay is resistant to corrosion and mechanical impact, suitable for demanding industrial environments. The wide operating temperature range from -40°C to +80°C ensures performance reliability in harsh conditions.

With an off-state leakage current of only 1 mArms and a low input/output capacitance of 8 pF, it delivers high-integrity signal transmission while maintaining electrical safety through a dielectric strength rated at 4000Vrms. Its compact size (58.4 mm length, 22.6 mm width, and 23 mm height) allows for efficient use of panel space in electrical control systems.

The HA4875 relay meets key standards including CSA, RoHS, and UR, underlining its compliance with international safety and quality regulations. It is ideal for industrial applications such as managing large-scale lighting systems, motor controls, HVAC systems, and manufacturing equipment where reliable and maintenance-free solid state switching is critical.

This Crydom product is manufactured in Mexico and features screw-type terminals for secure electrical connections. The device stops burning within 10 seconds or less during fault conditions, enhancing safety.
