Natupal Generator Interlock Kit for Siemens & Murray Panels (150A+) ECSBPK03

Product Overview

The Natupal Generator Interlock Kit is designed for Siemens and Murray panels with 150A or higher main breakers. It helps coordinate two power sources, directing generator power to selected circuits while preventing simultaneous operation of utility and standby power for safer, more flexible backup power management.

Compatibility and Fit

• Compatible with MBK150A, MBK200A, and MBK225A utility main breakers.
• Supports QP, QPH and HQPH standby main breakers as part of a streamlined backup solution.

Key Benefits at a Glance

• Easy installation with no extra control box or wiring required.
• Fits into your existing panel, offering a cost-effective alternative to a separate transfer switch.
• Mechanical interlock ensures that standby power and utility power are not energizing the same circuits at once.
• Durable, purpose-built components designed for long-term reliability in a home backup setup.

How It Works

When standby power is active, the utility main breaker is forced to OFF. When utility power is active, the standby source is forced to OFF. This straightforward mechanical action helps manage two power sources without manual reconfiguration during a power event.
