Compact Modular Recloser

Why Compact Modular Recloser (CMR)?

When overhead MV networks need fundamental protection and monitoring, the CMR delivers an integrated, self‑powered solution without pole‑mounted control cabinets, control cables or auxiliary supplies.

CMR integrates the vacuum interrupter, protection relay, controller and voltage powering in a compact, fully insulated unit. Lightweight design enables fast installation and commissioning, with wireless access and optional SCADA via a Remote Control Unit (RCU).

Single‑ and multi‑phase versions (up to 38 kV) suit urban and rural networks. Multi‑phase units offer three operating modes without physical reconfiguration for flexibility and inventory harmonization.

Remote Engineering Access (REA) supports secure remote configuration and event log/load profile downloads, with IEEE 1686‑2022 role‑based access control.

Key benefits

Eliminate auxiliary supplies with integrated design

Reduce infrastructure with a fully integrated, line‑voltage self‑powered recloser. For installs without SCADA, eliminate pole‑mounted control cabinets, cables and auxiliary supplies; add a RCU when SCADA is required.

Gain operational flexibility and control

Speed installation and commissioning with a compact, lightweight, fully insulated design that improves operator safety and supports deployment on urban and rural overhead MV networks.

Operate flexibly with wireless, SCADA and REA

Adapt protection and monitoring remotely or locally using wireless access and optional SCADA via RCU. Enable secure remote configuration and log downloads with REA and IEEE 1686‑2022 role‑based access control.

Remote Engineering Access (REA)

Remote configuration, monitoring and control using Siemens PC tools. Download event logs and load profiles for analysis without attending site; secured with IEEE 1686‑2022 role‑based access control.

Compact Modular Recloser (CMR) features a compact, fully insulated housing

Flexible SCADA integration (optional)

Choose a simplified installation without SCADA, connecting cables or auxiliary supplies, or add a Remote Control Unit (RCU) for SCADA integration. Wireless access supports safer configuration and operation.

Multi‑phase operating modes A/B/C

Two‑ and three‑phase CMRs operate in three modes (ganged or independent options). Modes can be changed without physical reconfiguration, supporting operating flexibility and inventory harmonization.
