ANSI Coil Gauge refers to the thickness of the steel wire used in mattress coils, measured according to standards set by the American National Standards Institute. A lower gauge number means thicker coils, which typically provide better support and durability for your mattress.
When shopping for a mattress, you might see a label indicating it has 13-gauge coils, which suggests a sturdier construction compared to a mattress with 15-gauge coils.
ANSI code 87B refers to bus differential relays, which are designed to protect busbars by monitoring the balance of currents entering and leaving. If an imbalance occurs due to a fault, the relay quickly isolates the affected section, minimizing disruption to the overall electrical system.
ANSI code 85 denotes a carrier relay, which is used for communication between protective devices over power lines. These relays help ensure coordinated protection by allowing devices to share information about system conditions and faults.
ANSI code 79 represents an automatic reclose relay, which is used to automatically restore power after a temporary fault has cleared. This feature enhances system reliability by reducing outage times and maintaining service continuity.
ANSI code 49 refers to thermal overload relays that monitor the temperature of electrical equipment to prevent overheating. When the temperature exceeds a set limit, the relay trips to disconnect the equipment, protecting it from damage due to sustained overcurrent conditions.
