ITE Siemens Q120 20 Amp Circuit Breaker

The ITE Siemens Q120 20 Amp Circuit Breaker is a single-pole plug-in circuit breaker used in Siemens and legacy ITE electrical panels and load centers. Also identified as the Siemens Q120 and QP 20 amp breaker, this breaker is rated for 20 amps at 120 volts and has a 10 kA interrupting rating. The Q120 is a thermal-magnetic circuit breaker designed for electrical distribution applications.

Electrical Supplies Unlimited has over 40 years of experience buying and selling electrical equipment. We buy and sell new, used, surplus, obsolete, discontinued, and hard-to-find ITE and Siemens circuit breakers. If you need an ITE Siemens Q120 for an existing electrical panel or replacement application, ESU can help locate the breaker you need.

ITE Siemens Q120 20 Amp Circuit Breakers for Sale

Electrical Supplies Unlimited buys and sells ITE Siemens Q120 20 amp circuit breakers for electrical contractors, electricians, businesses, commercial facilities, industrial customers, and other users. Depending on availability, ESU may have new, used, surplus, or hard-to-find Q120 breakers available.

The Siemens Q120 is a 20 amp, single-pole, 120V plug-in circuit breaker with a 10 kA interrupting rating. It uses a thermal-magnetic trip mechanism and is part of the Siemens QP/MP breaker family. The Q120 is UL 489 listed and designed for use in compatible Siemens electrical distribution equipment.

Because the Q120 is also commonly identified with the ITE Siemens name, it can be an important replacement option when maintaining older electrical panels. If you are replacing an existing breaker, provide ESU with the breaker number, panel information, or a photograph of the existing equipment whenever possible.

Used ITE Siemens Q120 20 Amp Circuit Breakers

A used ITE Siemens Q120 20 Amp circuit breaker can be an economical solution when maintaining an existing electrical panel. Used breakers are particularly useful when a customer needs to match an older installation or locate a breaker that may not be readily available through traditional electrical distribution channels.

Electrical Supplies Unlimited buys and sells used and surplus ITE and Siemens circuit breakers. Inventory changes frequently, so contact ESU with the Q120 catalog number and any information available from the existing panel.

Used electrical equipment should be inspected and evaluated by a qualified electrical professional before being placed into service. Breaker compatibility, condition, interrupting rating, and panel requirements should all be verified.

ITE Siemens Q120 Circuit Breaker Replacement

When replacing an ITE or Siemens Q120 breaker, matching the Q120 catalog number is an important starting point. The breaker should also be verified for amperage, voltage, number of poles, interrupting rating, mounting configuration, and compatibility with the existing panel.

Using a breaker simply because it has the same amperage rating does not necessarily make it a suitable replacement. Electrical panels are designed for specific breaker families and mounting configurations. If you are uncertain about the correct replacement, provide ESU with a photograph of the existing breaker and panel label.

Obsolete and Hard-to-Find ITE Siemens Circuit Breakers

Electrical Supplies Unlimited specializes in obsolete, discontinued, surplus, and hard-to-find circuit breakers. This makes ESU a useful resource when an older ITE or Siemens electrical panel requires a replacement breaker that is difficult to locate.

The ITE name is commonly associated with older Siemens electrical equipment, and customers may encounter ITE, ITE Siemens, Siemens, QP, MP, and other identifying information when searching for replacement breakers. Providing the original catalog number can make it much easier to identify the correct equipment.

If you have an older ITE or Siemens panel and need a Q120 or another hard-to-find breaker, contact ESU with the breaker number and panel information.
