Circuit breaker

The Square D DJM circuit breaker is designed to allow individual and multi-metered commercial structures with electrical systems rated at more than 18kA to use the company's 400A EZM branch devices. This circuit breaker allows for up to 100kA maximum fault current at 240VAC. Ideal for multi-floor office or residential buildings, the 3-pole breaker can be field-adjusted for current trip ratings between 160A and 400A.

Industrial luminaire

The Mercmaster III induction luminaire featuring QL induction technology is designed for hazardous and non-hazardous industrial lighting needs. The induction luminaire has a 20-year rated life or 100,000 hrs, and, even after 60,000 hrs, should maintain 70% of its total light output. Its other benefits include instant restrike, T3C “T Code,” no cycling at end-of-life, no flickering or stroboscopic effect, little or no sensitivity to power fluctuation, and harmonic distortion of less than 10%.

Measuring wheel

The SpeedMeter electronic measuring wheel is available in 4-in. and 13-in. wheel sizes. The wheel features a large LCD display, an electronic brake that holds the measurement until reset, and a telescoping handle to adjust for and facilitate storage. It can measure up to 10,000 ft/in., 10,000 yd/tenth, or 10,000 m/cm, and a touch button will convert any measurement. The unit adds the distance when going forward, and subtracts the distance when going backward. It is sealed to IP65/NEMA 4 specifications.

Soft starters

The Sirius 3RW40 and Sirius 3RW44 are multi-featured soft starters that can be used in a variety of start-up applications — from gently starting/stopping conveyor belts to hydraulic pumps. According to the company, the Sirius 3RW40 is half the size of a comparable wye-delta starter and can control two phases in the power range up to 300hp/460V. The Sirius 3RW44 is designed for more demanding motor starting applications, allowing it to start drives up to a power rating of 950hp/480V.

Cable cleaner

PF-200 and PF-400 cable cleaner is designed for splice and termination applications. These cleaners remove contaminants, residue, and conductive particles that can cause current leakage. PF-200 is nonflammable and fast evaporating, while PF-400 is low-odor, SNAP approved, free of chlorinated solvents, and has a high-flash point of 142°F. Both cleaners are non-conductive, non-corrosive, and non-staining.

Power distribution unit

This switched power distribution unit (PDU) incorporates amp metering that allows network administrators to control up to 16 outlets, reboot individual equipment, and monitor current and voltage all from a remote location. The PDU allows full or individually assigned access for up to 100 unique users, who can access, configure, and control the switched PDUs through the company's Web browser, command line interface, SNMP, or Telnet interfaces.

Current clamp meter

The AC50 leakage current clamp meter measures low AC currents to test ground conductors for leakage current down to 10 A. The meter also measures AC current to 60A and AC voltage to 400V. It offers a resistance measurement feature, a continuity beeper, and performs min/max and relative-value measurements. The compact meter is small enough to fit in a pocket, but has a wide jaw opening of 1.3 in.

High bay lighting system

The T8 high bay fluorescent lighting system was designed as an alternative to traditional HID and incandescent systems in high bay and open ceiling applications, such as gymnasiums, warehouses, manufacturing and industrial plants, distribution centers, and big box retailers. The lighting system purportedly provides 24,000 hours of lamp life and reduces energy costs by up to 60%. The company claims that the fixtures also provide better lumen maintenance — 94% at 40% rated life or design lumens — and better light uniformity.

AC drive

The G5HHP AC drive provides up to 1,750 hp for devices such as pumps, fans, chillers, mining conveyers, and rock crushers/extruders. The drive is designed as a modular system, providing separate sections for the converter and inverter. This allows the user to customize the drives from 400A to 1,600A ratings. The drive is equipped with a serial port using standard Modbus protocol and a user interface that allows access to all parameters, diagnostics, and operational commands. Its non-regenerative front end can support a 12-,18-, or 24-pulse configuration for harmonic reduction.
