TYPE 230-PM COMBINATION CONTROLLER
YPE 230-PM COMBINATION CONTROLLER
The type 230-PM controllers are for the control and protection of induction motors or transformers on 2400-4160volt systems. These controllers are especially designed for outdoor use in Class I, Division 2 hazardous locations.Each Type 230PM controller is a Class E2 coordinated combination of heavyduty vacuum contactor, thermal overload relay or multi-function protective relay, current transformers, and current-limiting fuses, with safety-interlocked isolating switch. To assure conformance to OSHA requirements, the basic design and most optional features have been reviewed and tested by UL.
IMPORTANT FEATURES & BENEFITS
- Vertical Equipment Arrangement for fast and safe maintenance
- Visible break Isolating Switch for maximum safety
- Vacuum break Contactor for long contact life
- Corrosion Resisting Design of All Components and Enclosure
- U. L. Review and Testing to assure compliance with safety standards
- Coordinated Design of Elliott manufactured Components
- Made in U.S.A. to ANSI/UL 347 Standard for Safety.
APPLICATIONS
GENERAL The 230‑PM controllers are for full‑voltage, non‑reversing, magnetic starting and protection of induction motors. Or they may be used to switch and protect transformers. Optionally, the contactor may be mechanically "latched" for transformer or feeder applications. Alternate designs are available for reduced‑voltage starting and for synchronous motor control.
FAULT CURRENT RATINGS The fault interrupting rating is 50 kA at 5,000 VAC. The main bus and ground bus are rated short time current 40 kA 0.167 seconds duration with rated momentary withstand current 62 kA/104 peak.
LOADS The 230‑PM controller is made in two continuous current ratings: 180‑amp and 360‑amp. These ratings typically may be used for control of induction motors up to 700‑HP and 1500‑HP at 2400‑volts or up to 1250‑HP and 2500‑HP at 4160‑volts, or higher HP depending upon service factor and locked rotor current. All controller ratings incorporate the same 360-amp contactor but differ in fuse sizes and cabinet arrangements.
LOCATION The 230‑PM controllers are particularly suited to outdoor installation and to other installations where protection from dust or corrosive conditions is desirable. The basic design and most optional features are suitable for Class I, Division 2, T3C hazardous locations.
