Eaton Specification Sheet - NZMH2-A100-BT-NA
Feature: Adjustable thermal and magnetic trip provides precise fault protection for a range of loads. Business Impact: By tuning trip characteristics to motor inrush, startup currents, and process variations, you reduce nuisance trips and extend equipment life, lowering maintenance costs. Application: Ideal for distribution panels serving motors, conveyors, and control circuits in manufacturing and packaging lines; supports fast recovery after faults, improving line uptime. This capability is especially valuable when you need consistent protection without compromising productivity. Feature: NZMH2 inside the NZM2 frame with front frame clamp and box terminals. Business Impact: The combination delivers robust, space-efficient mounting and dependable electrical connections that stay tight under vibration and temperature swings. Application: Suitable for compact switchgear and motor control centers where accessible wiring and reliable torque are essential; simplifies installation during panel builds and field retrofits. Feature: Short-circuit breaking capacity up to 150 kAIC and current-limiting performance. Business Impact: Higher fault current handling reduces the risk of cascading outages and supports safer upstream coordination, potentially lowering system-wide outage times. Application: Industrial facilities with higher fault energy, such as metalworking or presses, where protection must withstand short-circuit events without nuisance trips. Feature: Setting range OL protector 80-100 A and short-circuit release 600-1000 A delayed. Business Impact: Operators can tailor overload and short-circuit responses to process characteristics, ensuring protection while avoiding unnecessary disconnections. Application: feeders from distribution panels to machine controls, with deliberate adjustments during commissioning. Feature: Accessories including rocker lever and motor drive option; Business Impact: Improve manual operation, testing, and remote control compatibility, enabling automation schemes and easier maintenance. Application: panel builders looking to meet OEM requirements or to integrate with motors and drives, reducing commissioning time and improving reliability.
