MDI 35NO-120A Mercury Displacement Contactor, 35A, 120V Coil

MDI 35NO-120A Mercury Displacement Contactor

The MDI 35NO-120A is a heavy-duty mercury displacement contactor engineered for long-life performance in industrial switching applications. Its sealed mercury contact design ensures silent operation, high reliability, and exceptional durability across demanding environments.

Why It Helps
Hermetically sealed in a stainless-steel tube with inert gas, the 35NO-120A eliminates contact wear and bounce, delivering millions of dependable cycles. Its mercury technology provides clean, consistent switching for resistive heating and lighting loads without the noise or degradation typical of mechanical contactors.

Key Highlights

• Designed for high-current industrial use, the 35NO-120A handles up to 35A resistive loads with stable, bounce-free switching for long service life.

• The 120V coil operates efficiently with quick 50 ms engage and 80 ms release times for responsive control in automated systems.

• Encapsulated mercury contact ensures quiet operation, making it ideal where mechanical relay noise is undesirable.

• Industrial-grade terminals accommodate 4–14 AWG wiring with secure compression fittings for reliable installation.

System Compatibility
Compatible with resistive heating systems, industrial lighting controls, and single-phase motors within its rated capacity. Functions within control panels requiring silent, long-life switching.

Applications
Ideal for heating circuits, lamp loads, industrial machinery, and automated control systems requiring high-reliability switching. Offers robust long-term performance even under continuous industrial duty.
