Meltric Connectors for Pumps (NFPA70E)


meltric PUMP CONNECTORS
- No waiting for an electrician to perform field wiring
- No “suiting-up” or extraordinary electrical precautions
- Overload testing includes 50 opening and closing operations performed at 600% of full load motor ampacity with a power factor of 0.5 or less.
- All hp-rated Decontactor devices are rated to close into and withstand short circuit currents up to 100kA in circuits protected with RK1 fusing.
Note: Although Decontactor plugs and receptacles are rated to safely make and break motor loads, they are not rated or intended for continuous use as a motor starter.
Sections 430.102 – 430.109 of the National Electric Code require approved disconnecting means to be located in a readily accessible location within sight of the motor and driven equipment. With their UL & CSA ratings for “Motor Circuit Disconnect Switching” and “Branch Circuit Disconnect Switching”, Decontactor devices are an approved ‘line of sight’ disconnect switch for meeting this requirement.- 20A to 60A
- Max 20hp
- NEMA 4X
- Low Cost, Compact

Armstrong Astro 2 3-speed circulators provide unmatched performance over a wide range of head and flow requirements. The 3-speed design allows users to match the requirements of an installation exactly, and also helps with:
Reduced Inventory – the complete range of 10 Astro 2 3-speed circulators replaces 93 models of competitors’ pumps
Adaptability – After a circulator is installed you might need to change the performance to accommodate:
• Over/under estimated system resistance in the original design • Increased number of zones due to a building addition •Addition of system elements such as an indirect hot water tank or spa
With Astro 2 3-speed units installed you can easily change the operating speed to handle these changed performance requirements.
reduced installation costs
Astro 2 circulators (except sweat connection models) include a removable check valve that eliminates the need for additional check valves in the system. For replacement installations, the check valve can be removed as required.
compliance with lead-free regulations
Lead-free bronze and stainless steel models of Astro 2 certified <0.25 weighted average percent lead and complies with California Health and Safety Code Section 116875 (commonly known as AB1953).
3-speeds
Reduce your inventory with a variety of performance curves. Ten pumps replace 93 circulators. Correct design issues in the field by adjusting the circulator output.
removable check valve
Reduce costs by eliminating multiple system check valves. Helps prevent reverse flow and induced heat migration.
easy connection
Models are available with union, sweat or flange connections. Models are also available with rotated flanges for installation in tight locations, where clearance is an issue.
