Description
Built for high-density residential applications, this 15/40A quad breaker supplies two distinct 240V circuits from a single two-pole space. The unit incorporates a 40A inner pair and a 15A outer pair, making it ideal for adding new loads to full panels. It installs into Siemens and Murray load centers equipped with CTL rejection features. This model replaces the MP21540CT2. With a 10kAIC rating and common trip functionality on both circuit pairs, it ensures reliable thermal-magnetic protection.
