Securitron -u.s. MOV-50 Varistor Pack of 50

Product Description

The SECURITRON -U.S. MOV-50 is a varistor pack containing 50 individual metal oxide varistors (MOVs) designed to protect low-voltage access control and locking system circuits from voltage spikes and transient surges. MOVs are passive surge-suppression components installed across inductive loads such as magnetic locks, electric strikes, and solenoid-driven hardware. When a voltage transient exceeds the varistor clamping threshold, the MOV absorbs and dissipates the energy, protecting downstream control boards and wiring. This pack is sized for service technicians maintaining multiple doors or performing multi-unit installations.

The MOV-50 pack is used in commercial and light industrial access control installations wherever inductive loads are present on door hardware circuits. Typical applications include magnetic lock wiring, electric strike wiring, and relay coil protection in card-access or intercom-integrated systems. Sold in a quantity of 50, this pack suits ongoing service work or new construction projects where bulk component availability reduces callback risk from surge-related failures.

Key Features

• Pack of 50 varistors for multi-door or multi-unit installations
• Protects inductive load circuits from voltage transients and back-EMF
• Suitable for use with magnetic locks, electric strikes, and solenoid hardware
• Compact passive components with no external power requirement
• Sized for service technician inventory and new construction rough-in

Compatibility

Designed as an OEM-style accessory for use in low-voltage access control and door locking hardware circuits. No specific compatible model numbers were provided in the product data.

Installation Notes

MOVs in access control applications are typically installed by licensed low-voltage or electrical contractors following local codes and NEC requirements for Class 2 wiring. Always de-energize the door hardware circuit and discharge any stored energy in inductive loads before servicing connections. MOVs are wired in parallel across the load terminals; verify polarity requirements for the specific lock or strike hardware before installation. Do not install damaged or discolored varistors, as compromised MOVs may fail to provide surge protection.
