Zener Diode Barriers include features for hazardous areas.

info@productnews.com (ThomasNet News) — Tue, 17 Nov 2009 08:44:56 -0500

Offering both relay and solid-state switch models, MZB Series limits excess energy before it reaches hazardous area. Units feature removable terminals, bussed power feed, and channels as small as 6.3 mm wide. Each channel is fitted with 2 stages of pulse-tested Zener diodes and infallible terminating resistor. If electrical fault occurs in non-hazardous area of barrier, Zener diodes limit voltage available to hazardous area circuits, while series resistance limits current.

While PI/NI-2D/24 protects 24 V digital signals in case of short circuit or over-voltage condition, PI/NI-2I/I limits max short circuit current to 24 mA in 4-20 mA loops and can be installed with 2-wire 4-20 mA transmitters. Both use current and voltage limiting circuitry to minimize risk of ignition in hazardous Class I, Division 2 or Zone 2 environments. Analog and digital signal modules have 2 channels and can use INTERFACE T-Bus connection system.

Track Current Limiter is available in 4 models.

info@productnews.com (ThomasNet News) — Thu, 11 Sep 2008 07:34:18 -0500

Compliant with California Title 24 and ASHRAE 90.1 requirements, Track Current Limiter ensures that track installations meet wattage limitations according to size and usage of space. It can be mounted as standard canopy, used in place of I connector, or as live-end. Unit's circuit breaker will trip and shut down power to track when track is overloaded, and device may be reset when overall total of fixture wattages are reduced below circuit breaker rating.

Cable Limiters protect against short-circuit currents.

info@productnews.com (ThomasNet News) — Wed, 07 Dec 2005 07:05:20 -0500

Suited for copper and aluminum cables, Cable Limiters protect against short-circuit currents in residential and light commercial applications up to 250 Vac, as well as commercial and industrial applications up to 600 Vac. In single or multi-cable/phase applications, units provide current limiting short-circuit protection that minimizes potential hazards. In multi-cable/phase service entrance or grid network applications, limiters isolate faulted cables.
