Type SL fuses are time-delay plug fuses designed for circuits that supply motor loads and other inductive equipment subject to brief startup surges. The non-tamper construction prevents substitution with a higher-rated fuse, supporting code-compliant overcurrent protection. Licensed electricians and HVAC technicians install these fuses in residential and light-commercial fused disconnects, load centers, and service panels where standard Edison-base overcurrent protection is required.\u003c\/p\u003e\n\u003cp\u003eType SL plug fuses are commonly used in residential electrical panels and fused disconnect boxes serving HVAC equipment, appliances, and general branch circuits. The 20-amp rating covers typical 120-volt branch circuits for refrigerators, window air conditioners, and similar motor-driven loads. The non-tamper design limits the socket to fuses of the appropriate amperage, a requirement in many jurisdictions under the National Electrical Code for replacement fuse installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20-amp Type SL time-delay rating handles motor startup inrush without nuisance opening\u003c\/li\u003e\n  \u003cli\u003eNon-tamper construction restricts socket to correct amperage fuse per NEC requirements\u003c\/li\u003e\n  \u003cli\u003eSold as a 4-pack for convenient service call stocking\u003c\/li\u003e\n  \u003cli\u003eCompact boxed packaging at 2.31 inches L x 2.31 inches W x 1.31 inches H\u003c\/li\u003e\n  \u003cli\u003eEdison-base plug fuse format fits standard residential fuse panel sockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement Type SL plug fuse for standard Edison-base residential fuse panels and fused disconnects requiring a 20-amp non-tamper overcurrent device.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and replacement of plug fuses should be performed by a licensed electrician in accordance with applicable NEC requirements and local electrical codes. Always disconnect or de-energize the panel before removing or installing fuses. Verify the circuit voltage and amperage requirements before selecting the replacement fuse rating.
