Features:

  • Interface Between the Test Plug and MMLG 01 Test Block
  • Combines Capability of Current Handling with Safe Testing Support
  • Operates in Conjunction with the MMLG Series and Protection Systems
The Alstom MMLB01 operates as the multi-finger test plug in power system protection applications, providing reliable current handling capability for testing and verification purposes. It continuously supports up to 20 A continuous current or 400 A for 1 second across all contact circuits and operates at a maximum voltage of 300 V AC or DC under continuous conditions. The Alstom MMLB01 distributes test signals through its multi-finger configuration to support safe and controlled secondary injection testing of all protection schemes and monitors. Seamless integration with the MMLG 01 test block is standard with the Alstom MMLB01, allowing testing without disturbing existing protective wiring. The Alstom MMLB01 has been designed with IP20 protection rating to ensure basic protection against accidental contact in indoor environments.

The Alstom MMLB01 provides essential testing functions for protection systems, and is a critical component of the testing path, directly affecting the safe and effective operation of protection system testing and maintenance. One Alstom MMLB01 test plug is required per MMLG 01 test block for standard testing applications. The Alstom MMLB01 features a compact multi-finger design for easy insertion and removal from the test block.

For safe operation applications, the Alstom MMLB01 requires specific precautions to be observed during use. In addition to standard testing operation, the safety configuration also performs critical insulation verification. The Alstom MMLB01 safety system continually monitors the integrity of flying leads and short-circuit paths. If the system detects that terminals 13 and 14 are being used for CT connections (which may introduce potential safety risks), it will automatically prevent unsafe operation and require verification that all leads maintain adequate insulation and continuity before testing proceeds.

The MMLB01 Alstom multi-finger test plug may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
MMLB01 is a multi-finger test plug designed for use in power system protection and testing applications. It is primarily intended to operate in conjunction with the MMLG 01 test block, allowing testing and verification of protection systems without the need to disturb existing protective wiring. Through this configuration, MMLB01 supports efficient monitoring of protection schemes and enables secondary injection testing in a safe and controlled manner.

In terms of electrical performance, MMLB01 provides reliable current handling capability across all contact circuits, supporting up to 20 A continuous current or 400 A for 1 second. The maximum operating voltage of MMLB01 is rated at 300 V AC or DC under continuous conditions, making it suitable for typical protection and test circuit requirements. The device is designed with an IP20 degree of protection, ensuring basic protection against accidental contact in indoor environments.

For safe operation, specific precautions must be observed when using MMLB01. Terminals 13 and 14 must not be used for CT connections, as this may introduce potential safety risks. Before use, it is essential to verify that all flying leads are properly insulated and that the plug and associated short-circuit paths maintain adequate insulation and continuity. Adhering to these guidelines ensures that MMLB01 can be used safely and effectively during protection system testing and maintenance.
