Schneider CVS100BS-80A: Product Description and Specifications
Schneider CVS100BS-80A is a disjoncteur à boîtier moulé (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.
je. Spécifications de base
1. Rated Current and Frame Size
Courant nominal: 80UN, 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); Tension d'isolation nominale: 690V; Impulse Withstand Voltage: 8kV.
Capacité de coupure (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. Caractéristiques fonctionnelles
1. Fonctions de protection
Protection contre les surcharges: The thermal element has an adjustable setting range of 0.7~1 times the rated current (c'est-à-dire, 56~80A), adapting to different load characteristics.
Protection contre les courts-circuits: The magnetic element has a fixed instantaneous tripping value of 640A (8 fois le courant nominal), enabling rapid fault interruption.
Fonction d'isolement: The open position complies with the IEC 60947-2 standard, providing safe maintenance conditions.
2. Installation and Operation
Méthodes d'installation: Supports fixed mounting (configuration standard) 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).
Méthode de câblage: Front-panel wiring design, simplifying the wiring process in switchgear.
Méthode de fonctionnement: Manual toggle handle, supporting direct operation or extended rotating handle expansion.
3. Fiabilité et Certifications
Durée de vie mécanique: 30,000 operating cycles; Durée de vie électrique: 12,000 cycles (at 415V).
Normes de certification: 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.
Déclenchement de dérivation (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. Scénarios d'application
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, systèmes d'éclairage, 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. Référence de prix
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. Précautions
Cascading Application: Refer to the cascading table provided by Schneider to ensure safe coordination between upstream and downstream circuit breakers.
Température ambiante: The 80A rated current is suitable for a 40℃ environment; derating is required for use in high-temperature environments.
Compatibilité des accessoires: Some accessories need to match the circuit breaker model; it is recommended to consult Schneider technical support directly.
