TECHNICAL OVERVIEW

Purpose and operating principle.

LMZ current limiting resistors are built for high thermal and mechanical duty, with resistor construction and enclosure options selected around the required current limitation, environmental conditions and installation constraints.

KEY FEATURES

Application-driven characteristics and selection criteria.

Typical applications include high-power test laboratories and motor starting.

Used in electric arc furnaces and induction furnaces.

Stainless-steel grid resistor elements.

2 mm hot-dip galvanized steel enclosure available on demand.

High thermal capacity, rugged shock-resistant construction and high-altitude capability.

Special designs can be developed for hazardous or extreme locations in line with applicable IEC and IEEE requirements.

RESISTOR SYSTEMS

Electrical and thermal duty define the final resistor configuration.

LMZ resistor systems are selected around the network, current, voltage, thermal duty, operating cycle and environmental requirements of the application.
