Eaton EMN24 W20 0 Manual Line Starter - Hazardous Locations
Part Number: EMN24 W20 0
Quick Summary
EMN24 W20 0 manual line starter provides reliable motor control in hazardous locations across industrial facilities. In field installs, mismatched starters, heater maintenance, and complex wiring frequently slow start-up and raise safety risk. This unit is built for NEC/CEC compliance and UL hazardous-location listings, featuring Class I Division 1 and Division 2 across the ratings, plus robust NEMA ratings 3, 7, 9, and 12. Copper-free aluminum construction keeps weight manageable while enduring demanding environments. The compact NEMA size 0 enclosure fits small control panels and supports two-pole, single-phase operation for 1 hp or 2 hp motors at 115/208/240 Vac. With the heater omitted, maintenance costs drop and failure modes reduce, delivering reliable, low-maintenance control for mission-critical line-start applications.

FAQs
EMN24 W20 0 is designed for two-pole, single-phase operation and supports motors rated at 1 hp or 2 hp across 115, 208, and 240 Vac. This provides flexibility for mixed supply environments and simplifies procurement since a single starter covers typical small motor loads. It is ideal for retrofits or new installations needing multi-voltage compatibility without extensive rewiring.
EMN24 W20 0 carries NEC/CEC compliance and UL hazardous-location certifications for Class I Division 1 and Division 2 across ratings, plus compatible NEMA ratings 3, 7, 9, 12. This combination supports regulatory compliance, safer installations, and easier audits in oil/gas, chemical processing, mining, and other hazardous environments. Site-specific area classifications and local codes should always be observed.
Yes. The two-pole, single-phase EMN24 W20 0 is rated for 1 hp/2 hp motors and uses a NEMA size 0 enclosure that fits compact control panels. Copper-free aluminum reduces weight, and omitting the heater minimizes maintenance and potential failure modes, making it ideal for tight installations in hazardous locations.
Mounting should follow standard EMN installation practices with the included enclosure, ensuring proper wiring to the two-pole starter at 115/208/240 Vac. The equipment’s area classification and UL/NEC approvals guide selection, wiring methods, and enclosure protection. Ensure proper conduit sealing, grounding, and clearance per NEC and local codes to maintain safe operation.
With the heater omitted, routine maintenance is simplified, reducing spare parts and potential heater failures in hazardous environments. This can lower maintenance downtime and extend starter life, contributing to a favorable return on investment. If heater control becomes a requirement later, evaluate compatible accessory options from Eaton’s EMN series.
