The Siemens GF222NRA is a fusible safety switch categorized under the VBII Safety Switches series. This unit effectively operates with a rated current up to 60 A, accommodating voltages of 240 V AC at a maximum and 250 V DC. It integrates two poles and three wires, making it versatile for various wiring configurations.
Compatible with Class H and Class R fuses, the switch ensures optimal protection in electrical circuits. Importantly, its short-circuit rating reaches 10,000 A RMS symmetrical when fitted with Class R fuses, providing significant safeguarding capabilities. The enclosure is designed to meet NEMA Type 3R standards, allowing for use in rain-prone environments.
For horsepower applications, it supports up to 3 HP at 240 V AC for single-phase circuits and 7.5 HP for three-phase circuits. A consistent application in 250 V DC circuits can also handle up to 3 HP. It's crucial to observe that for continuous load current, the limit is set to 80% of the fuse rating in non-motor circuits. Additionally, the GF222NRA is suitable for service equipment use, offering flexibility for installation and application across various industrial settings.
