The AMETEK BW Controls 8040UC3F1RTML3N115 is supplied as a single PUMP combination starter relay panel with DISCONNECTS. It is an Automatic Alternator relay or pump-control panel from AMETEK BW Controls, used to alternate or sequence multiple pumps so wear is distributed evenly and a duty/standby arrangement is maintained.

BW Controls' automatic alternator products switch which pump in a multi-pump station runs first on each call for service, so no single pump carries the full duty cycle while the others sit idle. This is commonly paired with float or conductivity level switches that signal when pumping is required, with the alternator relay deciding which pump, or pumps in a fixed-sequence arrangement, responds. AMETEK supports parts such as the 8040UC3F1RTML3N115 as part of a broader catalog of industrial instrumentation and electromechanical components, sourced to match the original fit, form, and function of the unit being replaced.

Key Features and Specifications:

• Manufactured by AMETEK BW Controls
• Identified by AMETEK part number 8040UC3F1RTML3N115

When replacing pump-control hardware in a lift station or sump system, the 8040UC3F1RTML3N115 is matched against the original panel's pump count, voltage, and sequencing arrangement to ensure the alternator continues to rotate duty pumps correctly.
