Product Type: Hydraulic Magnetic Circuit Breakers

ADR Series

A new standard for DIN rail-mounting hydraulic-magnetic circuit breakers. The Heinemann ADR series is the evident choice for manufacturers willing to integrate their design with hydraulic-magnetic technology without additional redesign effort. In addition to all the advantages of hydraulic-magnetic circuit breakers such as precise, stable, and reliable protection against overload or short-circuits, ADR provides the same Fit and Form as standard MCB: a great advantage for simplifying refurbishment or technology upgrade.

Features

  • Hydraulic-magnetic overcurrent and fast short-circuit protections
  • Different tripping curves
  • In-Rush capabilities (8x – 15x – 22xIn) in standard
  • Changeover (SPDT) auxiliary contact (C-NO-NC) embedded on the same pole as the circuit breaker
  • Different configurations and types of auxiliary contact connections
  • Midtrip options: handle falls to horizontal position on electrical tripping
  • Trip-free design: breaker cannot be defeated by holding the handle in the ON position
  • Power to the circuit breakers can be fed from the line or load side
  • Easy installation on DIN 35mm rail according to DIN 50022 (IEC/EN60715)
  • Module width of only 17.5 mm (per pole)
  • Captive screws cannot be lost
  • Captive terminals
  • Optional handle locking system for Logout/Tagout

C Series

The C Series is popular in outdoor locations, in either high-temperature or low-temperature environments where nuisance tripping might have been a problem in the past. The C Series is built for a wide range of applications and is one of the most versatile designs. From heating and air conditioning to modern railcars, the C Series breaker is built for the most demanding industrial applications.

Features

  • Environmental, Vibration, and Shock Resistant: Mil-spec qualification for fungus resistance, humidity, salt spray resistance, and shock vibration resistance.
  • Heat-Induced Nuisance Tripping Eliminated: The protector is designed to “hold in” at 100% continuous rated current, regardless of ambient temperatures from -40°C +85°C.
  • Immediate Reset After Trip: The protector can be reset (closed) immediately after an overcurrent trip without a “cooling off” period.
  • 1/2 Cycle High Inrush Tolerance – 8X (standard) and 25x: The protector is available with different levels of tolerance to 1/2 cycle current spikes. Standard tolerance is 8X the continuous current rating; in addition, 25X is also available.
  • Overcurrent Curves, Long, Medium, or Short Delay: Time characteristic curves are available as Short, Medium, and Long Delay.

GH Series

The GH Series breaker offers the benefits of hydraulic-magnetic protection in a compact, economical design. Because of their ability to furnish both close-rated locked rotor protection and running overcurrent protection without derating in extreme and highly variable ambient conditions, they are popular in a variety of industries — air conditioning, electric heating, computer main frame and central processing, transportation, and many others.

Features

  • Fungus and Humidity Resistance: Provided in accordance with MIL-STD-202 by treating all ferrous parts with a special moisture-resistant finish and using special springs and fungus-resistant cases, covers, and handles.
  • Shock: Tested in accordance with MIL-STD-202, Method 213, Test Condition I (100G’s at 6 milliseconds).
  • Vibration: Tested in accordance with MIL-STD-202, Method 204, 10 to 500 Hz, 0.06-inch total excursion on three mutually perpendicular planes. Shock and vibration tests apply to time delay breakers only and are performed with units carrying full rated current.
