HYDRAULIC MAGNETIC CIRCUIT PROTECTORS
Introduction
Designed specifically for the 35mm symmetrical DIN rail, Airpax IALHR, IULHR and IELHR series Rail-Mount Magnetic circuit protectors offer the
advantages of quick and easy mounting or removal which results in efficient and economical wiring, while conserving space.
These circuit protectors are available in 1, 2, 3 and 4 pole models, with a choice of handle colors with on/off and international I/O markings. These
protectors comply with UL and CSA standards and meet IEC and VDE spacing requirements. Typical applications include computers and peripherals,
telecommunications, medical equipment, machine tools and process control instrumentation. They provide the reliable performance associated with
magnetic circuit protection.
Mounting - These circuit protectors are designed to mount on standard
35mm DIN rails, such as 35x7.5 or 35x15 per DIN EN50022. Other
specialty rails are available from suppliers that provide a means of
mounting non DIN mount components by means of special captive jam
nuts.

SPECIFICATIONS
Series Trip
The most popular configuration for magnetic protectors is the series trip where the sensing coil and
contacts are in series with the load being protected. The handle position conveniently indicates circuit
status. In addition to providing conventional overcurrent protection, it’s simultaneously used as an on-off
switch.
Switch Only
In the event that over-current protection is not desired, the coil mechanism can be deleted, providing an
excellent low cost, single or multi-pole power switch.
Insulation Resistance
100 megohm minimum at 500Vdc between all electrically isolated terminals.
Dielectric Strength
3750Vac (3750V~) shall withstand AC voltages 50/60Hz for 60 seconds between all electrically isolated
terminals.
Endurance
Circuit breakers shall operate a minimum of 10,000 operations; 6,000 with rated current and voltage and
4,000 with no load.
Operating Temperature
–40°C to +85°C.
IEC 144 Classification
Type handle spacings–IP40. Terminals–IP00.
