This switch is designed for marine applications and is suitable for systems up to 48 volts DC.<\/p>\n<p>The terminal bolts are made of tinned copper for maximum conductivity and optimal corrosion resistance. Thanks to the one-piece bolt design, the connections stay firmly in place even under prolonged vibrations or high current loads.<\/p>\n<p>The insulating protective cover with breakable cable openings protects the connections from short circuits and allows cable entry from different directions. With a continuous load of 300 amps and a peak capacity of up to 900 amps, this main switch is suitable for heavy-duty electrical installations onboard.<\/p>\n<p><strong>Main Benefits<\/strong><\/p>\n<ul>\n<li>Safe main switch for battery installations<\/li>\n<li>Continuous load up to 300 A<\/li>\n<li>Peak load up to 900 A<\/li>\n<li>Tinned copper terminal bolts<\/li>\n<li>Corrosion-resistant design<\/li>\n<li>Protective cover against short circuits<\/li>\n<li>Cable entry from multiple directions<\/li>\n<li>Suitable for heavy-duty electrical systems<\/li>\n<li>Vibration-resistant construction<\/li>\n<li>Water-resistant to IP66<\/li>\n<li><strong>Technical Data<\/strong><\/li>\n<li>Model: SFCBS-300-202<\/li>\n<\/ul>\n<p>Type: Battery switch ON\/OFF<\/p>\n<ul>\n<li>Max. voltage: 48 V DC<\/li>\n<li>Continuous current: 300 A<\/li>\n<li>Intermittent: 500 A (5 min)<\/li>\n<li>Start peak: 900 A (30 sec)<\/li>\n<li>Terminal bolts: M10 (3\/8&#8243;)<\/li>\n<li>Max. torque: 13.56 Nm<\/li>\n<li>Protection class: IP66<\/li>\n<li>Certifications: CE, RoHS, ISO 8846, UL1500, SAE J1171<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Heavy-duty <strong data-start=\"1293\" data-end=\"1323\">SEAFLO battery switch 300A<\/strong> for safe power interruption of onboard systems.
