Siemens be4 Insulated Bussed Elbow 1200A 240VAC Nema 1

Product Description

The SIEMENS be4 is an insulated bussed elbow designed for use with PowerMod Modular Metering systems. It provides a secure, high-current bus connection point within modular metering assemblies, handling up to 1200 amps at 240 volts AC in 3-phase, 4-wire configurations. Rated for 100 kA interrupting capacity, this component is built for demanding commercial and industrial metering applications. Installation is along a 15-inch mounting rail, and the unit includes one Quick Connect fitting for simplified field assembly. Electricians and metering specialists rely on this elbow to maintain bus integrity across modular sections in NEMA 1 indoor enclosures.

The SIEMENS be4 is intended for indoor applications where PowerMod Modular Metering sections must be joined at an angle or transitioned within a metering stack. Its insulated construction keeps adjacent bus conductors isolated, reducing arc and fault risk in high-density meter center configurations. The NEMA 1 rating suits dry indoor environments typical of commercial buildings, multi-tenant residential, and light industrial facilities. Metering contractors and licensed electricians install this component as part of a larger modular metering assembly rather than as a standalone unit.

Key Features

• 1200-amp continuous current rating for high-load metering applications
• Insulated bussed elbow design keeps conductors isolated and reduces fault exposure
• 100 kA interrupting capacity meets demanding short-circuit protection requirements
• 3-phase, 4-wire configuration supports standard commercial power distribution
• Includes one Quick Connect fitting for faster field assembly
• Mounts to 15-inch mounting rail within PowerMod Modular Metering systems

Compatibility

Designed for use with PowerMod Modular Metering systems as stated by the manufacturer. Suitable for indoor NEMA 1 installations only.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the entire metering assembly and verify zero voltage with a calibrated meter before handling bus components. This elbow is a structural bus component within a modular metering stack and must be aligned to the mounting rail before securing. Do not attempt to modify the insulated bus surfaces or use this component outside its rated voltage and current envelope.
