Heinemann Electric - CANADA

Heinemann has introduced many new products to the Hydraulic/Magnetic Circuit Breaker product line, extending its capability while maintaining its compact size.

Hydraulic Magnetic Circuit Breakers  Heinemann hydraulic-magnetic circuit breakers are available in both AC and DC ratings in accordance with UL, CSA and VDE standards. Heinemann offers a number of equipment, branch and main circuit breaker products that meet American, European and Asian agency listings, ensuring products designed with Heinemann may be designed, built and sold worldwide.
The hydraulic-magnetic circuit breakers may be configured with a variety of non-delayed or time-delayed trip characteristics. Heinemann hydraulic-magnetic circuit breakers carry 100% rated current even at elevated temperatures and will trip instantaneously upon short-circuit. The breaker overload-trips according to a time-delay versus overload current trip curve. High in-rush configurations are also available for protecting loads like distribution transformers and power supplies.  The Heinemann hydraulic-magnetic circuit breaker is the original hydraulic magnetic circuit and equipment protector that offers three major advantages over thermal devices.


  • Ability to carry 100% of rated current without nuisance tripping at elevated temperatures
  • Withstand current inrush without overload tripping
  • Unique construction provides precise trip characteristics across a broad temperature range 

Heinemann breakers are available in circuit configurations such as the commonly-used Series Trip; Dual Rating for tripping at two discrete current ratings; Relay Trip for remote trip actuation isolated from the line voltage and Shunt Tap for remote tripping using the line voltage. An integrated auxiliary switch is available for remote alarm applications. Also available are a variety of screw, stud, clip and plug-in terminal options. Several handle color, marking and location options are also available.

Agency recognition or approvals include: UL; CSA; SEV; VDE; IEC & CE.
