Note on Dimensions: Terminal hole sizes are Ø22 mm (0.9 in) for 3P and 4P main terminals. Mounting dimensions are provided for reference.

Accessory Installation

Various accessories can be installed, including auxiliary contacts, shunt trip units, and alarm contacts. Refer to the diagrams for specific installation steps and part numbers.

• Auxiliary Contacts: Part numbers include LV429261 (3P), LV429262 (4P) for CVS100, and LV431563 (3P), LV431564 (4P) for CVS160/250. Installation involves clipping them onto the breaker.
• Shunt Trip Units: Part numbers include LV429263 (3P), LV429264 (4P) for CVS160/250. Installation involves mounting them on the side of the breaker.
• Connection Kits: Kits like LV429235 (3P/4P) and LV429236 (3P/4P) are used for connecting accessories. Installation involves attaching parts A and B with M6 x 20 screws, torqued to 5 N.m (44 lb-in).
• Cable Entry Covers: Part numbers LV429515 (3P), LV429516 (4P) for CVS100, and LV429517 (3P), LV429518 (4P) for CVS160/250.
