Siemens Q21530CT 15/30/30/15 Amp Triplex Circuit Breaker – Type QT

Description

The Siemens Q21530CT is a space-saving Type QT triplex circuit breaker designed for compatible Siemens load centers. It combines two outer 15 Amp single-pole circuits with one inner 30 Amp double-pole common-trip circuit while occupying only two panel spaces. Siemens rates it for 120/240V AC with a standard 10,000 AIC interrupting rating.

This breaker is intended for Siemens panels specifically marked to accept CTL Type QT breakers. Its plug-in design makes it useful where additional circuit capacity is needed without using four full breaker spaces.
