378240 COMPONENT SPECIFICATIONS FOR BPU.pdf

This document contains product specifications for electrical equipment components required for a federal contract procurement. The specification document outlines three main categories of equipment: electric panel boards, main circuit breakers, and motor starters.

The electric panel board specifications detail two designations (A and B) of I-Line MB Panel (Interior) Panelboards. Designation A consists of a 480Y/277V 3-phase 4-wire 60Hz SCCR 65kA panelboard with a 600A/3P main circuit breaker, padlock-capable main disconnect, and three incoming feeder positions (3/0 to 500 kcmil copper conductors). The panel features a 68H x 42W x 9.5D Type 1 enclosure with surface-mounted door and includes standard copper bus bars and mechanical restraint provisions. Designation B is a similar 480Y/277V 3-phase panelboard with a 600A/3P main circuit breaker rated for 72 mounting inches, featuring a 91H x 32W x 9.5D Type 1 enclosure. Both panels include specified feeder configurations, standard nameplates with black surface and white lettering (3.50" Wide x 1.00" High), and enclosure/cover/trim assemblies with corresponding catalog numbers and drawing references.

The main circuit breaker specification describes a PJL3612DYP-Molded Case Circuit Breaker with UL/CSA rating, PowerPact P Frame, and 3-pole configuration rated at 600 Vac with 80% standard rating. The breaker accommodates interrupting ratings of 100kA @ 240V and 95kA @ 480V with 600 Vac capacity and provides handle padlock attachment options. The motor starter specifications include two NEMA Size designations—Size 2 (25 HP @ 460V 3-phase) and Size 4 (100 HP @ 460V 3-phase)—both featuring thermal magnetic circuit breaker combination starters with Class 8539 ratings, non-reversing 3-pole configurations, Type 1 enclosures, fused control transformers with 120V 60Hz coils, dual control fuses (primary and secondary), auxiliary contacts (normally open and closed), and pilot light assemblies with HAND-OFF-AUTO selector switches and LED status indicators.
