It serves as the interface for alarm signaling in motor control circuits, providing a dedicated contact block for bell alarm functions. Classified as a modular accessory (Family / Style: Modular), it integrates into the MS325 platform without additional panel wiring for the alarm circuit — the contact block mounts directly to the starter housing. ## Integration into MS325 motor starter assembly The left side mount orientation means the contact block holder attaches to the left flank of the MS325 starter body, preserving the right side for other accessories (e.g., auxiliary contact blocks). This modular stacking keeps the overall footprint compact within the panel. As a bell alarm contact block, it provides a normally open or normally closed signal path that changes state when the starter's overload mechanism trips — used to trigger an audible or visual alarm in the control room or PLC input.","metaTitle":"ABB MS325-SK10 Contact Block Holder, Bell Alarm","metaDescription":"ABB MS325-SK10 bell alarm contact block holder for MS325 motor starters.
