VOLTALUME VL-MTS-G1Z Series Manual Transfer Switch — Dependable manual dual-source switching for critical distribution boards.
The VOLTALUME VL-MTS-G1Z is a manual transfer switch built for industrial and enterprise power distribution equipment, rated AC 50/60Hz up to 400V with conventional thermal current up to 3200A. It handles infrequent making and breaking between two power sources plus electrical isolation, to IEC 60947-3 and GB/T 14048.3 — a straightforward, operator-controlled alternative where full automatic transfer isn’t required.
Key Features
- Full current range: 63A to 3200A in one series
- Rated insulation voltage up to 1000V, impulse withstand up to 10kV
- Dual use-category rating: AC-22B (lower frames) and AC-21B (higher frames)
- Rated short-circuit making capacity up to 105kA
- Manual dual-source switching with isolation function
