CUTLER HAMMER DND50SD14 DND Series Thermal Magnetic MCCB, 2P 50A 240VAC

Overview

The CUTLER HAMMER DND50SD14 is a Series C DND frame molded case circuit breaker with thermal-magnetic trip. It offers overload and short-circuit protection, widely stocked as spare for factory branch circuits and HVAC distribution panels.

Features

This DND breaker has fixed thermal-magnetic trip characteristic, supports reverse feed and auxiliary/ shunt trip accessories. The DND50SD14 adopts lug connection, compact unit mount design and UL489 certification. It is a legacy Eaton Cutler-Hammer distribution breaker.

Specs

Model: DND50SD14 Series: Cutler-Hammer DND Type: thermal magnetic molded case circuit breaker Poles: 2 Rated current: 50A Rated voltage: 240VAC Mounting: unit mount Connection: lug terminal Certifications: UL, CSA, CE Product status: obsolete power distribution spare

Principle

The thermal bimetallic element trips for sustained overload, while the magnetic element instantly triggers the mechanism under short-circuit current. The mechanism isolates the downstream fault circuit and shows trip status visually.

Applications

The DND50SD14 is widely deployed in factory panels, HVAC skids and small machine power distribution boards. It is used for overload and short-circuit protection for motors and general loads.
