TYPE 230 COMBINATION CONTROLLER
The type 230 controller is a 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. The power elements are arranged vertically, for easy and safe installation and maintenance. Each controller requires only a 20-inch square of floor space. 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 type 230 controller provides full-voltage, non-reversing, magnetic starting and protection for inductions motors. Or it may be used to switch and protect transformers.
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.
LOCATIONS The type 230 is ideal for indoor locations. In a minimum floor space, the design provides the safety and maintainability of on-high construction. The type 230 needs only 2.78 square feet of floor space with working space required only in the front of the controller.
LOADS The type 230 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.
