Schneider CVS100BS-80A

 Schneider CVS100BS-80A: Product Description and Specifications

Schneider CVS100BS-80A is a molded case circuit breaker (MCCB) belonging to the EasyPact CVS series. It is mainly used for overload and short-circuit protection in low-voltage power distribution systems, and is suitable for residential, building, and small-to-medium industrial scenarios.

 I. Basic Specifications

 1. Rated Current and Frame Size

Rated Current: 80A, compatible with a 100A frame size (CVS100BS), supporting system expansion for higher current loads.

Trip Unit Type: Thermal-magnetic (TM-D), providing both overload long-time delay protection (thermal element) and short-circuit instantaneous protection (magnetic element).

 2. Voltage and Breaking Capacity

Rated Operational Voltage: AC 440V (covering common industrial voltages); Rated Insulation Voltage: 690V; Impulse Withstand Voltage: 8kV.

Breaking Capacity (Icu) varies with voltage:

  - 40kA at 220/240V (suitable for residential and general commercial environments);

  - 25kA at 380/415V (meeting the needs of small-to-medium industrial applications).

 II. Functional Features

 1. Protection Functions

Overload Protection: The thermal element has an adjustable setting range of 0.7~1 times the rated current (i.e., 56~80A), adapting to different load characteristics.

Short-Circuit Protection: The magnetic element has a fixed instantaneous tripping value of 640A (8 times the rated current), enabling rapid fault interruption.

Isolation Function: The open position complies with the IEC 60947-2 standard, providing safe maintenance conditions.

 2. Installation and Operation

Installation Methods: Supports fixed mounting (standard configuration) and plug-in mounting (additional accessories required). It can be installed horizontally, vertically, or upside down (upside-down installation is only supported for fixed mounting).

Wiring Method: Front-panel wiring design, simplifying the wiring process in switchgear.

Operation Method: Manual toggle handle, supporting direct operation or extended rotating handle expansion.

3. Reliability and Certifications

Mechanical Life: 30,000 operating cycles; Electrical Life: 12,000 cycles (at 415V).

Certification Standards: Complies with international and regional standards such as IEC 60947-2 and CCC, applicable to most markets worldwide.

 III. Accessory Expansion

 1. Control and Indication Accessories

Auxiliary Switch (EZAUX10): Provides opening/closing status signals, supporting remote monitoring.

Shunt Trip (MX): Enables remote control of circuit breaker opening, used for fire linkage or emergency power cutoff.

Undervoltage Trip (MN): Automatically opens the circuit when voltage is abnormal, protecting downstream equipment.

 2. Earth Leakage Protection Module

- The VigiCVS earth leakage accessory can be added, providing 30/100/300mA earth leakage protection and supporting alarm-only (non-tripping) or direct tripping modes.

 IV. Application Scenarios

Residential and Commercial Buildings: Used as the main switch in distribution boxes or for branch circuit protection, adapting to 220/240V low-voltage environments.

Small-to-Medium Industry: Protects motors, lighting systems, and main power distribution lines, compatible with 380/415V industrial voltages.

Replacement Solution: Fully compatible in size with Schneider's NSE series, enabling seamless replacement of old models and reducing transformation costs.

 V. Selection and Procurement

 1. Model Identification Interpretation

CVS100BS-80A: CVS series, 100A frame size, breaking capacity class B (25kA@415V), 3 poles, TM-D trip unit, 80A rated current.

Order Number Examples: LV510844 (3P), LV510316 (4P).

 2. Price Reference

Domestic Market Unit Price: Approximately 500~600 RMB (for 3P models). The price of 4P models is slightly higher; specific prices are subject to distributor quotations.

 VI. Precautions

Cascading Application: Refer to the cascading table provided by Schneider to ensure safe coordination between upstream and downstream circuit breakers.

Ambient Temperature: The 80A rated current is suitable for a 40℃ environment; derating is required for use in high-temperature environments.

Accessory Compatibility: Some accessories need to match the circuit breaker model; it is recommended to consult Schneider technical support directly.
