The Schneider Electric VZ7 is an auxiliary contact block designed for TeSys VARIO switch-disconnectors, offering 1 normally open (NO) and 1 normally closed (NC) contact. This module is compatible with TeSys VARIO switch bodies ranging from V02 to V6, providing flexibility in various applications. The VZ7 is engineered for high performance, featuring a late-make NO contact and an early-break NC contact, ensuring reliable operation in diverse electrical environments. It supports both AC and DC networks operating at 50/60 Hz, with a rated operational voltage of up to 690 V AC and a rated impulse withstand voltage of 8 kV. The conventional free air thermal current is 12 A, and the conventional enclosed thermal current is 10 A, accommodating a wide range of electrical loads. Designed for durability, the VZ7 boasts a mechanical durability of 100,000 cycles and an electrical durability of 30,000 cycles for DC-11 and 100,000 cycles for AC-15, ensuring long-term reliability. The module features screw clamp terminals suitable for flexible cables with cable ends (0.75 to 1.5 mm²) and solid cables (1 to 2.5 mm²), with a tightening torque of 0.7 N.m. Its compact dimensions (65 mm height, 20 mm width, and 48.5 mm depth) and lightweight design (0.05 kg) facilitate easy integration into existing systems. The VZ7 complies with international standards, including IEC 60947-5, and holds certifications from GL, CSA, UL, and UKCA, ensuring adherence to global quality and safety standards. It operates effectively in ambient temperatures ranging from -20°C to 50°C, with an IP20 degree of protection conforming to IEC 60529, making it suitable for various industrial environments.
