Description:

The Zinsco QCAL-60 N is a 60 Amp, 2-pole molded case circuit breaker designed for use in Zinsco / GTE Sylvania load centers. It operates on 240V systems and uses a thermal-magnetic trip mechanism to provide protection against overloads and short circuits. This breaker belongs to the QCAL (QC/QCAL series) and features a plug-in (snap-in) mounting style for installation in compatible panels. Typical specifications for this model include a 10 kA interrupt rating at 240V, standard thermal-magnetic protection, and compatibility with legacy Zinsco panelboards.

Applications:

The Zinsco QCAL-60 breaker is commonly used in residential and light commercial electrical systems for 240V branch circuits requiring 60A protection, such as HVAC systems, electric ranges, subpanels, water heaters, and large appliance loads. It is intended for use in older Zinsco panels and is primarily utilized today for maintenance or replacement of existing installations.
